What if your stage crew child doesn't take algebra 2/trig? or physics?

My friend thought about getting a rescore but after discussing the test with the boy and the tutor, they decided it wasn’t worth it. He took the SAT a couple of weeks and they are going to see how he does on that. The math tutor thought ACT was a better choice for my son but that SAT would be better for my friend’s son. He has a 3.8 and is a talented musician on a not as popular instrument so he has other things going for him.
